Dear all. I am facing problems with IN2 Infusion Epoxy resin pigmented with Dust grey WS26121A. Applying wet laid process and after 24h, the epoxy has not cured. The weight of the components is the following: 125g (IN2 infusion epoxy), 37,5g (AT30 slow), 17,5g (dust grey WS26121A). I made trials with the same epoxy with TiO2 to obtain white coloured sheet and the curing was correct after 15h. Can somebody give me an explanation about this problem? I would appreciate a prompt answer as I have to produce some prototypes as soon as possible. Thanks to all. Andreu
